On the other hand, the all-at-once analysis of the path integral naturally looks at the entire history of the experiment. In spacetime, the six photons are connected in a \(\mathtt {\vee {}\hspace{-3.5pt}\vee {}\hspace{-14.9pt}{\mathchoice{\scalebox {2}[1]{\displaystyle }}{\scalebox {2}[1]{\textstyle }}{\scalebox {2}[1]{\scriptstyle }}{\scalebox {2}[1]{\scriptscriptstyle }}}}\)  pattern, where the three final vertices are linked via the experiment in essentially the same manner as the three initial vertices. Viewed holistically, it would be far less difficult to explain a violation of Eqn. (REF ). After all, one would not assume that the final vertices would remain uncorrelated from such an interconnection, and by the same argument some global all-at-once rule could correlate certain hidden parameters on the initial vertices. Given the connections along the photon worldlines, such an explanation would not appear to require direct space-like influence. In other words, the path integral account of these experiments does not generally treat them as “nonlocal”, but rather as evidence that the entire histories must be analyzed via all-at-once rules as advocated in [1]}, [2]}, [3]}.
